To all whom it may concern;

Be it known that LSAM K. IVERSQN, a citizen of the United. States,v residing at Colfax, in the county of Dunn, State of Wisconsin, have invented certain newand useful Improvements in Spraying Attachments; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i e i This invention relates to spraying attachments for cultivators and has for an object to provide means for supplying a spray of insect poisoning fluid to plants being cultivated, at the will of the operator.

A further object is to provide a fluid reservoir having novel air compressing means actuated by one of the cultivator ground wheels or the axle, forfeeding the insecticide under pressure through the spray nozzle.

' A further object is to provide an extremely simple and inexpensive apparatus of this character which may be applied to all ordinary cultivators and which will be compact in form and inconspicuous, and

which will be light, strong and durable and will consist of a few parts that will not easily get out of-order. 1

With the above objects in View the invention consists ofcertain novel details of construction and combination. of parts hereunderstood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawings illustrating this invention: Figure 1 is a side elevation of a cultivator equipped with my invention. Fig. 2 is a plan View. Fig. 3 is. a cross sectional view on the line 3-3 Fig. 1 with parts removed. Fig. i is a cross sectional View on the line 41 Fig. 2. Fig. 5 is a cross sectional view on the line 55 Fig. 2. Fig. 6 is a detail longitudinal sectional view on the line 66 Fig. 1. Fig. 7 is a side elevation showing the pump actuating rod in the position it assumes to accommodate tilting forward of the axle. Fig. 8 is a detail perspective view of the cam wheel.

Referring now to the drawings in which like characters of reference designate similar parts, 10 designates in general an ordinary cultivator.

The spraying attachment comprises a res ervoir 11 which is suspended underneath the l jacent to the cultivatoraxle 22, and from directly downwardly as shown 26 that is equipped which projects through one end of the pump the top of the reservoir by means of U-bolts 31, the

reservoir is. equipped in the bottom with an outlet pipe 18 that is carried upwardly adthe front of the seat and there supported by means of a bracket 19 secured to the cultivator frame, the pipe being at this point equipped with a valve 20 which is controlled by a lever 21 disposed within convenient reach of the operator. The pipe is then led forwardly to a point in advance of this point at 23 and terminally equipped with a spray nozzle 24; that is arranged midway between the ground wheels'of the cultivator and slightly above the treads of the wheels.

For supplying the liquid from the reser- :VOlI under pressure, a pump cylinder 25 is disposed on the bottom of the reservoir and within this cylinder works a pump piston with a piston rod 27 cylinder, there being an air pipe 28 communicating with the opposite end of the pump cylinder and entering the top of the inafter fully described and claimed, it being reservoir. Asafety valve 29 is disposed on which valve opens under excess pressure in the reservoir. For actuating the pump piston I provide a wheel 30 that is disposed on the cultivator axle near oneofthe ground wheels and is secured for turning with said ground wheel wheel being equipped on the periphery with a spiral cam rib 32. A rod 33 is pivoted to swing in a horizontal plane on a coupling 34 attached to the upright portion of the axle 22 next adjacent to the cam wheel 30, by means of a vertical pivot pin 35, this rod being braced by an upwardly inclined brace 36 which is hinged on a vertical pivot pin 37 that is in vertical alinement with the pivot pin 35 and is carried by a coupling 38 secured to the upright portion of the axle 22 as best shown in Fig. 1.

A cross arm 39 is pivotally connected by a bolt 40 to the rod 33 and is terminally equipped with spaced rollers 41 which ride 1 v tively perform its 4L6 is hinged to rotation of the cam wheel by the adjacent round wheel of the harrow, the cross arm i ocks the rod 33 horizontally. The cross arm is normally held in operative position by means of a helical spring 42 attached to the rod 33 and to the opposite end of the cross arm from the rollers. For disconnecting the cross arm from the cam wheel 30 a lever 43 is pivoted on the rod 33 and is connected by a link li to the cross arm adjacent to the. rollers, there being a catch lug d5 on the side of the rod 33 over which the lever maybe rocked rearwardly and engaged in rear thereof to withdraw the cross arm and seopingly fits, the link 49 being provided with a longitudinal slot 50. A connecting link 51 is pivotally connected to the piston rod 27 as shown at 52 and is equipped with i i a pin 53 which fits in the slot 50 of the link 49. A straight rod 54; is pivotally connected as shown at 55 to the free end of the link 49 and is also pivotally connected as shown at I 56' to the'rod 33 near its vertical pivot 35.

I Gopies of this patent may be obtained for Now when the axle is tilted forwardly the hinged ends of the rod 33 and link 46 rise vertically as shown in Fig. 7, the link 46 moving outwardly from the link 4:9 to per- I mit of this movement. By virtue of the pivotal connections between the ends of the rod 54: and the rod 33 and link 49, the rod 33 and link 49 are permitted to move as above described while, the length of the rod 56L five cents Washington, D 0.

remaining constant, a constant distance is maintained between the connecting pin 53 of the pump'piston and forward end of the rod 5% ma straight line whereby the actuation of the pump piston is continued regardlesls of the tilted position assumed by the ax e.

i In operation the cultivator is drawn along over the rows of plants in the usual manner with a resultant actuating of the pump and resultant charging of the tank with air,

the pressure of which is regulated by the release valve 29. When itis desired to spray the plants to kill insects thereon, the operator simply presses the valve lever 21 to open the valve.. The poison fluid is then discharged under pressure through the spray nozzle and thoroughly sprays the desired plant.

What is claimed, is j 1, The combination with an'air pump of a swinging'rod connected to the pump piston, the said rod including a jointed portion and a reach bar bridging the jointed portion and connecting the ends thereof, a pivot at an extremity of the r0d,'across bar on the rod near said pivot, and a cam operatively engaging the'bar. V

' 2. The combination with an airrpump, a horizontally swinging rod connected to the pump piston for operating said piston, said rod comprising a jointed portion and a reach bar bridging the joint of and connesting the ends of; said jointed portion, a verticalpivot for one end of said rod, a cross bar on said rod near-said pivot, and a-cam operatively engaging said bar for shifting the latter back and forth horizontally to swing said rod horizontally.

In testimony whereof, I'aflix my signature, in the presence of two witnesses.
